Keep in mind that Jiskha ...

... doesn't do students' assignments for them, and
... doesn't have answers to give away and wouldn't do so even if we did!

To determine the correct answer between options A and B for Bedford exercise #4 12-27, we need to identify the sentence structure and analyze the placement of the different elements.

Option A:
"After buying an album by Ali Farka Toure, Silas understood the rich and rolling rhythms of Malian music."

Option B:
"The rich and rolling rhythms of Malian music after Silas bought an album by Ali Farka Toure."

To identify the correct answer, we need to look at the cause-effect relationship between Silas buying an album and understanding the music.

In option A, the sentence follows the logical order of events. Silas first buys the album, and then, as a result of that action, understands the rich and rolling rhythms of Malian music. This cause-effect relationship is clear and accurate.

In option B, the sentence is structured differently. It states that the rich and rolling rhythms of Malian music occur after Silas bought an album. This sentence doesn't establish a direct cause-effect relationship between buying the album and understanding the music. Therefore, option B does not convey the same meaning as option A and is therefore not the correct answer.

In conclusion, the correct answer is option A: "After buying an album by Ali Farka Toure, Silas understood the rich and rolling rhythms of Malian music."
